A record of two Wakeari couples who applied for a certain company's swapping service. Mr. and Mrs. Maeda, who have a calm atmosphere and conflicting sexual preferences, and Mr. and Mrs. Ueda, who are full of curiosity. Judging by the CPU that they are a good match, they indulge in a different kind of pleasure far removed from their daily lives. The texture of his skin is different from that of his own wife, the passionate caress is different from that of her husband, and the foolery with strangers that unfolds in front of him. A terrifying excitement runs through the whole body, and the climax is engraved many times. Knowing the pleasure that goes beyond the work of a couple, they open up new ground without hesitation.
